<p class="under">This text has a line underneath it.</p>
<p class="over">This text has a line over it.</p>
<p class="line">This text has a line going through it.</p>
<p>This <a class="plain" href="#">link will not be underlined</a>,
    as links generally are by default. Be careful with removing
    the text decoration on anchors since users often depend on
    the underline to denote hyperlinks.</p>
<p class="underover">This text has lines above <em>and</em> below it.</p>
<p class="blink">This text might blink for you,
    depending on the browser you use.</p>
